One incident. One question:
can you prove you covered your duties?
Screens show sample data.
Your whole daily routine, in one app. Harness inspections that tell you when it's time to inspect. POWRA forms that tell you when there's an issue.
Swipe to see each form →






Every form feeds the same record, automatically.
Not on a paper form that doesn't get looked at until the job's done. Photo evidence attached on the spot and time-stamped the moment it's submitted — geotagged too, where the phone allows. Not typed up later back in the site cabin.
Harness & lanyard inspection
PUWER inspection
Every operative, every site, up to date whenever you open it — harness defects, overdue inspections and expiring qualifications flagged on one screen. Log a renewal course once it's booked, and track it through to the result.
Flagged POWRAs, failed equipment checks and defects are emailed to your team as they happen, and chased if a POWRA flag stays unresolved. Handover certificates and weekly HSEQ reports go straight to the site contacts you choose, such as the principal contractor. On private jobs, send the handover certificate to the customer by WhatsApp.
POWRAs and handover certificates save on the phone when there's no coverage. Queued forms show on your dashboard, ready to send with one tap when you're back in signal.
CISRS, SSSTS, SMSTS, MEWP and plant tickets, and any other qualification you add, tracked for every operative.
Give a named site contact read-only access to that site's completed documents. No login to set up, and you can switch it off at any time.
Invite users, set roles, assign supervisors to sites and arrange holiday cover yourself, from the Admin section.
Working on a job that isn't a set-up site? Record it as other works and it still appears on your dashboard and in your records.
You own everything you record, and it stays on the system for as long as you're a customer. Hosted in the UK and Germany (email delivery uses a US provider under UK-approved safeguards), and SOS is registered with the ICO. If you leave, we'll export it on request, PDFs included, for 30 days after.
Everyone's emergency contact on your dashboard, with the number ready to call in one tap. Managers see their whole workforce; supervisors see everyone signed on to their site today.
Your logo, colours and address on every PDF. The same handover certificate for three different companies.
One button compiles your compliance records for any site, company-wide and/or date range into a single PDF, ready to hand to your principal contractor or wherever you need it. Commercial tier and above.
No app store and no passwords. Everyone signs in with a secure link emailed to them and lands on the screen built for their role. Add it to your phone's home screen and it opens like an app.
A secure link is emailed to each person, so there are no passwords to lose. Managers, H&S and supervisors each get their own dashboard.
CISRS card, employment status, emergency contact, harness and lanyard details, recorded once. Every form then links back to the right person.
Create sites as you win them. New sites come with sensible inspection schedules you can change per site.
Tell us a bit about your business and we'll get back to you — no generic sales deck, just a straight conversation about what SOS would replace for you.
